Central Iowa

A burst of colorful farm machinery is surrounded by demonstration fields at the Central Iowa Expo in Boone this week. The Farm Progress Show is attracting thousands of farmers, agronomists and agribusiness representatives. It’s an annual trade event that alternates between the Iowa site and Decatur, Illinois.

A winter snow storm dumped several inches of unexpected snow on the Des Moines area Tuesday morning, much of it during the morning rush hour. Forecasters are adjusting their predictions as more snow moves into the region.

National Weather Service Meteorologist Jeff Johnson says the storm's trajectory defied predictions, which had put most of the snowfall in southeast Iowa.
